First off I like how you made the teacher's information a seperate page at the start so students don't need to be bothered reading about the details.
This is a great idea for students to practice their letter sounds!!! It first focuses on isolated vowel sounds then works on stretching the sounds in order to make words. There is also a review at the end for further practice. I was so bummed when the sounds didn't work on my computer :(
I receive a "codec unavailable" rejection when I try to play the sounds.
